Title: Hitch for single wheel bicycle trailers
Inventor: LAWRENCE ROGER CHARLES
IPC: B62K27/12
Filed: 1996-01-05
Abstract: A pair of link pieces B and C are joined as hinges with pins G set in vertical axes to adaptor blocks H which can rotate on stub axles (not shown) fixed either side of, and parallel to the axis of, the bicycle rear wheel. The link pieces are also joined by pins F to lugs D, which are welded to the ends of encircling arms A extending from the trailer on either side of the bicycle rear wheel. Hence, bicycle and trailer can articulate in two axes, but not in a third axis. Blocks H may be removed from the stub axles to disconnect the trailer; handles (K and L, fig. 2) may be provided on the trailer to allow it to be used independently as a barrow. Folding legs M allow the combination to be propped upright.

Title: Measurement of velocity from motion picture signals
Inventor: NOMURA MASAHIDE
IPC: G06T7/20
Filed: 1996-03-15
Abstract: A motion picture signal from a camera 1 is processed by a spatiotemporal filter to obtain an optical flow of a concerned object. The velocity of this object is measured from the optical flow. Picture signals are digitized and transformed by a 2D FFT section 4, followed by a first spatiotemporal filter 5, convolution section 6 and second spatiotemporal filter 7. Each spatiotemporal filter consists of MxN spatial filters and MxN temporal filters. The first spatial filter uses an integration kernel localized on a smaller spatial domain than that of the second spatial filter. The output of the first filter section is a power distribution of local spatiotemporal energy (local optical flow component) and the output of the convolution section is a local optical flow distribution. The second filter section calculates an optical flow distribution from which a velocity distribution for each pixel is obtained and the object corresponding to the calculated velocity is identified.

Title: Value metering system employing RF communications for enhanced security and functionality
Inventor: MANDULEY FLAVIO M
IPC: G07B17/00
Filed: 1996-07-02
Abstract: A value metering system 202 (such as a franking machine or postage meter) stores an unique identification code 224 to enable it to be identified from a plurality of other value metering systems. Communications means 218 receives broadcast communication messages from a remote data centre. The broadcast communication may be by radio frequency. The received messages are processed to determine if they are intended for that particular value metering system 202. If so, then the controller 204 controls the operation of the value metering system. For example, in a franking machine this may be to disable or enable printing, or to update postal rates.

Title: I.c. engine with catalytic converters and some cylinders capable of being shut down in part-load operation
Inventor: GUNTHER JOSEF
IPC: F02M26/43
Filed: 1997-03-18
Abstract: The multi-cylinder piston-type i.c. engine has two cylinder groups 2, 3, each having respective exhaust lines 4, 5 which are connected downstream of parallel catalytic converters (cats.) 6, 7. In part-load operation, one cylinder group 3 is shut down. In order to heat the cat. 7 of the shut-down cylinder group 3 to operating temperature within a very short time after transition from part-load to full-load operation without additional sources of heat, at least some of the exhaust gases from line 4 are diverted into line 5 via common pipe section 9 so that exhaust gases pass through cat.7 in direction 18. This can be achieved by opening the exhaust valves and closing the inlet valves of the shut-down cylinder group 3 so that group 3 acts as a vacuum device 11 until cat. 7 reaches its operating temperature. An exhaust gas recirculation 13, fig 4, may connect the exhaust line 5 of the shut-down cylinders 3 to the intake of the firing cylinders 2 via shut-off valve 14.

Title: A fuel injection valve with a spill passage to shape the injection profile
Inventor: MATTA GEORGE M
IPC: F02M45/08
Filed: 1997-12-11
Abstract: A hydraulically actuated fuel injector comprises a fuel pressurisation chamber 70, a nozzle chamber 73 housing a needle valve 80, a nozzle supply passage 71 connecting the pressurisation chamber 70 to the nozzle chamber 73, a fuel return passage 87 connecting the nozzle chamber 73 to a drain and a spill passage 72 branching from the nozzle supply passage 71 leading to the nozzle chamber 73 which is blocked and unblocked by the needle valve 80 during the injection cycle. The spill passage 72 is blocked when the needle valve is in the fully closed and fully open positions and all fuel flows to the nozzle chamber and from there discharged to a combustion chamber. When the needle valve 80 is moving from the closed position to the open position the spill passage 72 is temporarily opened allowing fuel to flow through the spill passage 72 via annulus 82 to the return passage 87 thus temporarily reducing mass flow and pressure in the nozzle chamber 73 and hence producing a desirable front end rate shaping of the injection profile. The return passage 87 may in part have a large volume to prevent cavitation.

Title: Method of forming a masking or spacer pattern on a substrate using inkjet droplet deposition
Inventor: SPEAKMAN STUART PHILIP
IPC: G03F1/00
Filed: 1999-05-27
Abstract: A masking pattern (Fig.25) or a spacer pattern (Fig.27) is formed on a substrate by droplet ejection of a deposition material (e.g. solder) on to the substrate to form the pattern which comprises multiple discrete or coalesced extended portions. The droplets once deposited are cured by electromagnetic radiation (e.g. ultra violet, visible light, infra red, microwaves and alpha-particles) delivered by a source (e.g. a lamp or a laser integrated on a printhead, Fig.7). A method to form a circuit pattern on a circuit board using droplet deposition is disclosed (Fig.21) wherein the droplets are deposited to partially fill holes formed in the board. A method to form a relief pattern on a substrate is disclosed wherein the method involves the steps of selectively irradiating a charged roller to selectively remove the charge on portions of the roller, depositing material (e.g. microcapsules,particles,beads) on to the charged portions of the roller, and transferring the deposited material from the roller on to the substrate to form the relief pattern thereon. Finally, a droplet deposition apparatus is disclosed which includes an ion implanted wiper blade (Fig.13) which periodically cleans a nozzle outlet of the deposition apparatus.

Abstract: A conventional circuit for blocking a semiconductor switching device (7) on overcurrent, the semiconductor switching device (7) having at least one continuously driven semiconductor switch (9), comprises a driver circuit (11), which has a driver stage (12) for each semiconductor switch (9), a control pulse generator (10) For producing control pulses (P 1  to P 6 ), which are fed in operation to a control input of the semiconductor switching device (7) via the driver circuit (11), and a monitoring device (34), which measures the current (I) flowing through the semiconductor switching device (7) and, when an overcurrent occurs, generates a fault signal (E), which initiates blocking of the semiconductor switching device (7). When the semiconductor switching device is being blocked, a high overvoltage can occur therein, possibly leading to destruction of the semiconductor switching device. In order to reduce, with little outlay, the overvoltage in the semiconductor switching device during blocking thereof, provision is made such that the operating voltage (U) of the driver circuit (11) is arranged to be switched over briefly by the fault signal to a lower, interim value corresponding to a lower current (I) through the semiconductor switching device (7) and then, within the maximum permissible duration for loading the semiconductor switching device (7) with an overcurrent, to be switched off completely.
